I came from Arch to Void just today and after installing KDE and enabling dbus, I enabled SDDM, I type in my password and it says login failed, I tried lightdm, I couldn't login neither in my user account nor root, I setup plasma to run with xinit, plasma did launch successfully, but sudo NEVER worked inside plasma, it always says "password incorrect, please try again" even though I'm able to sudo inside TTYs

I tried "sudo sddm" and read the logs, it says SDDM: authentication_FAILED for user "" which is weird (it didn't print any names)

There were also some PAM logs in between, I didn't change any PAM configuration

I have elogind installed and enabled too

I'm building a sw that should be able to read the papers read from a scanner and process them with a minimal user interaction, basically I don't want the user to jump into another sw, output an image or doc, and insert that into my sw, this kind of problem seems to be fixed when it comes to printers printing, but I couldn't find something similar for scanners (paper scanners especially, I have no use for QR and barcode scanners), the best I could find is USB HID interface, which seems pretty low level and if I'm not wrong device-specific so I have to write the implementation for each model I need to support (please correct me if I'm wrong), I know this is a Linux community but does Windows have something similar too (my sw will probably need to run on it)

Sorry if this isn't the most suitable community

So I've messed up by not formatting my partitions on installation and now things are buggy, dbus returns permission denied on starting is one of the prominent bugs at the moment

Two days ago, I did a fresh Arch install, everything went fine, then I changed my mind about my HDD partitioning and reformatted it, and installed Arch again, the install boots okay and all, but NetworkManager was down, when I investigated it, I found out that dbus service fails to start here is what systemctl status dbus returns:

dbus-broker-launch[383]: launcher_add_services @ ../dbus-broker-35/src/launch/launcher.c +805 dbus-broker-launch[383]: launcher_run @ ../dbus-broker-35/src/launch/launcher.c +1416 dbus-broker-launch[383]: run @ ../dbus-broker-35/src/launch/main.c +152 dbus-broker-launch[383]: main @ ../dbus-broker-35/src/launch/main.c +178 dbus-broker-launch[383]: Exiting due to fatal error: -107

I've run journalctl with some filtering and found this too:

systemd-tmpfiles[327]: Detected unsafe path transition / (owned by 999) -> /var (owned by root) during canonicalization of var/lib/dbus systemd-tmpfiles[327]: Detected unsafe path transition / (owned by 999) -> /run (owned by root) during canonicalization of run/dbus

I ran ls / -l and found out that my boot partition is owned by a user named 999 and group adm (what the hell is this?)

I've tried installing dbus-daemon-units and remove dbus-broker and dbus-broker-units, now I got a different problem which was that dbus was timing out on start, so the problem might not be caused by dbus itself, I really don't want to reinstall Arch again, I'm chrooting into my install for internet connection too

So I've had enough from partitioning my HDD between Linux and Windows, and I want to go full Linux, my laptop is low end and I tend to keep some development services alive when I work on stuff (like MariaDB's) so I decided to split my HDD into three partitions, a distro (Arch) for my dev stuff, a distro (Pop OS) for gaming, and a huge shared home partition, what are the disadvantages of using a shared home (yes with a shared profile, I still want to access my Steam library from Arch if I want that)

Another thing that concerns me is GRUB, usually when I'm dualbooting with Windows, the Linux distro takes care of the grub stuff, should only a single distro take care of GRUB? or I need to install "the grub package" on both? Do both distros need separate boot partitions? Or a single one for a single distro (like a main distro) will suffice?

Another off topic question, my HDD is partitioned to oblivion, can I safely delete ALL partitions? Including the EFI one? I'm not on a MacBook, a typical 2014 Toshiba that's my laptop
